Version 0.1.2

This release introduces a powerful new feature called the LLM Committee, enabling multi-model consultation with parallel querying, peer review, and synthesized responses. It also includes retroactive release notes for previous versions and improvements to the release note generation process.

New Features

  • Implemented the LLM Committee feature that allows querying multiple language models simultaneously, includes a peer review stage where models critique each other, and synthesizes the final response via a chairman model. This includes backend SSE endpoint, frontend modal for model selection, and streaming UI with stop controls. (f46fdf) (Eric Ma)
  • Added retroactive release notes for versions 0.1.0 and 0.1.1 to improve documentation and changelog completeness. (38bb01) (Eric Ma)
  • Integrated LLM-generated release notes using llamabot in the auto-release workflow, automating the generation and storage of release notes for future versions. (357656) (Eric Ma)

Version 0.1.1

This release brings major improvements to the Canvas Chat experience, including a robust CI/CD pipeline, automatic PyPI publishing, a refactored Python package structure, and significant enhancements to the force-directed layout and node overlap handling. It also introduces LLM-generated release notes, improved test coverage, and a more reliable and maintainable codebase.

New Features

  • Add LLM-generated release notes using llamabot, with automated storage and GitHub release integration. (116346, Eric Ma)
  • Add tests workflow for Python (3.11, 3.12, 3.13) and JavaScript, and update all GitHub Actions to latest versions. (9155ef, Eric Ma)
  • Add automatic PyPI publishing on merge to main, with trusted publishing and version management. (e3afef, Eric Ma)
  • Refactor to a proper Python package structure for PyPI publishing, including CLI entry point and improved test imports. (f836a6, Eric Ma)

Bug Fixes

  • Fix force-directed layout edge spring to respect node sizes, preventing large nodes from overlapping when connected by edges. (7ff72f, Eric Ma)
  • Fix force-directed layout overlap detection for rectangles, ensuring repulsion only when bounding boxes actually intersect. (7c2ca1, Eric Ma)
  • Fix resolveOverlaps to properly separate large nodes, improving convergence speed and correctness for heavily overlapping nodes. (53686c, Eric Ma)
  • Fix handleNodeResummarize to use correct streaming pattern, and document API verification steps for agents. (3367d9, Eric Ma)

Deprecations

  • No deprecations in this release.

Version 0.1.0

This is the initial release of Canvas Chat, a visual non-linear chat interface where conversations are nodes on an infinite canvas, allowing branching, merging, and exploration of topics as a directed acyclic graph (DAG).

Core Features

  • Infinite Canvas: Pan and zoom interface with native trackpad/touch gesture support for navigating conversations
  • Node-based Conversations: Chat messages rendered as draggable, resizable nodes with support for branching and merging
  • Multi-model Support: Works with OpenAI, Anthropic Claude, Google, Groq, GitHub Copilot, and local Ollama models
  • Session Management: Create, save, and switch between multiple canvas sessions
